I have a rooted OnePlus 5 on the latest beta and I'm trying to flash back to the latest stable OOS through TWRP. When TWRP starts, it asks for a decryption password which I never set -- I have a lockscreen pattern. I made the mistake of trying to flash with a pattern and face unlock. Is there a workaround for this? I tried to sideload another stable zip but for some reason I get an "System.ui has crashed" error. Can anyone help?
